Abstract

Planar wavcguides were made from a linear epoxy copolymer of bisphcnol-A diglycidyl ether and amino-nitro-tolanc. The refractive indices, ni-M and n-E, and the clectrooptic coeflicients, r33 and r13, of the poled nonlinear optical polymcr films were determined by measurements of the wavcguide modes of these films at a wavelength of 632.8nm, and the results arc reported for both electrode and corona poling. The ratio of the second order susceptibilities was found to exceed significantly the theoretically expected value of 3. Restricted motion of the nonlinear chromophorcs during poling provides a possible explanation of this discrepancy.
